The water pump on a 1991 Subaru Legacy is in the engine compartment. It is found at the base of the engine.
in with the timing belt change them at the same time
For the heater core. All cars have them.
See your user manual, its great for help with all the basic maintenance
You need to burp the radiator and cooling system.
looking for info on locating water pump and timing belt on 99 subaru outback 2.5 liter motor, hopefully with a diagram...thank you
Check the 1991 Legacy for a stuck thermostat. Check to make sure that the water pump is working properly.
a 50/50 mix of good quality antifreeze and water
Water pump is run by the timing belt. So, you have to do everything required to replace the timing belt plus a few more capscrews that hold the pump in. These should be done at the same time, 10 years or 100,000 miles, which ever comes first.
Same problem turned out to be a hair line fracture to the head!
Go to: http://opposedforces.com/parts/legacy/us_b12/ Select Body Style, Engine Type, Transmission, etc. Go to Cooling System. Select Water Pump; You should find Thermostat, Gasket & applicable part numbers...
Yes. You cannot see the water pump because it is in position to be driven by the timing belt. Always replace then together.
ok 1990-1994 subaru legacy engines are basically the same the water pump on mine 1991 is located on the thermostat housing on the bottom of the engine on the lower tube off the radiator so find your lower radiator hose follow it is should go to the thermostat and the water pump is on that
it is in front of the engine block under the water pump kinda low on the engine

Generally it is recommended replacing the timing belt and water pump on a 4 cylinder Subaru engine at 10 years or 100,000 miles, which ever comes first.
Genuine Subaru Coolant or equivalent (50% water & 50% Ethylene-Glycol basis coolant) as per page 10-13 of the "OWNER'S MANUAL".....
The torque should be around 11 ft-pounds
A local library may have the repair manual.
Head gasket is probably blown. Water is passing out through exhaust. This is a common problem with subarus
Classic "air bound". Start engine, leave off rad cap, turn heater all the way up, open plastic vent on opposite side of radiator, and slowly fill with coolant.
replace heater core. replace fan.
Not good. Head gasket or cracked head. Exaust is getting into the water jacket somewhere. blown head gasket, or cracked head.
Bad seal around the bottom of the wind shield maybe?
I have a 07 legacy doing the same thing. I flushed the heater core by romoving the hoses and running pressured (water hose) water through the heater core. refilled heater core with hoses off to remove any air bubles. heats on both sides now.
